White dots... Just once.

The lens wasn't changed between shots and the camera was brand new (a couple fo days), so dust on sensor would be improbable. There are several images taken in quick succession and this is the only one where this occurred, so I'm inclined to go with the hypothesis of dust or drops of sweat in the air.

As for PP creating the dots: it's not a matter of "creating" them, but rather of enhancing something. Sure enough, if I load the image without any post processing, the dots are not visible. It's when I push the blacks up and add a bit of clarity (+15 in LR) that they show up.

As you can imagine, I was worried when I noticed this for the first time. But since I also noticed it had something to do with pp and didn't show up on any other pics, I'm not worried anymore. Just a tad curious about about the causes. :)

Seems quite a reasonable explanation. It is true that this only shows up after processing. Though it may be not from sharpening, but, according to my own experiment with pp settings, due to pushing up shadows and adding a bit of clarity. So perhaps all combined. I first thoug of tiny bits of sand thrown up...

Thanks for the input.

Can be... But the following shots don't show them, although nothing was changed in between. That's what I find odd.

Hi, all

I recently received my K-1 and I'm quite impressed with it.

There is, nevertheless, an issue that's been troubling me: it shows-up in one of a series of shots (just a couple of days after receiving it) of a "capoeira" demonstration at the beach nearby where I live.

They all came out fine (except for the photographer's errors...), but on this one, when viewed at 100%, a strange splash of white dots appear in a section of the shot. I annexed the shot and a 100% crop of the section.

None of the other several shots taken at the same location, with the same settings, etc., show this - which is quite intriguing. Of course I have seen reports of the infamous "white dot" issue, but it does not seem to be an issue at ISO 200, which was the ISO at which this photo was taken.

Any ideas why this happened?

(PS. - I always shoot RAW. This apperas afeter processing, both in Lightroom and Capture One 10).

Your guesses are welcome!
